Throwout bearing for 5.3 swap

[SixPointTwo]

I'm currently dealing with this:

But the rep at Summit Racing thinks my Exedy clutch came with the wrong throwout bearing and that I should get this one instead (which is listed as fitting my truck):

which should work for my 350ci that's in the truck now. Tranny is a '92 5LM60.

But the real question is, while I'm planning ahead, I know my Exedy clutch kit will fit on the 5.3 as long as I use the Sachs NFW1050 flywheel, will the N1716 throwout bearing work? I had always heard that you need the N1086 throwout bearing for the 5.3 swap:

But it looks totally different than the others. Anyone have any input?
